CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional PatentApplication Ser. No. 61/184,467, filed Jun. 5, 2009, entitled“Ruttenberg's Hinge Drumstick”, the entire disclosure of which isincorporated by reference herein.

BACKGROUND OF THE INVENTION

This invention relates in general to musical percussion instruments, andmore particularly to drumsticks for playing percussion instruments.

Drumsticks typically include a butt end, a striking end, and anintermediate region located in between the butt end and the striking endalong the length of the body of the drumstick. The intermediate regiongenerally includes a balance point about which the drumstick pivots whenthe tip or striking point of the drumstick rebounds from contact with adrum skin.

The drumstick is generally held at or near the balance point during use,since gripping the stick at this point generally minimizes the dampingof the stick's movement as it strikes and then rebounds from the surface(i.e. skin) of a drum or other percussion device. In order to properlytrain students learning to play percussion instruments, such as, forinstance, a snare drum, it is helpful not only to aid the student ingrasping the stick at the balance point, but to encourage gripping ofthe stick in the proper manner. The latter is of particular importancein learning a technique in which the stick is effectively hinged betweenthe thumb and forefinger of the user's hand, and the last three fingersof the hand controlling the rate of movement of the stick about thehinge formed by the thumb and forefinger.

Drumsticks have been devised which attempt to minimize damping orrestraint on the motion of the drumstick, for example, by isolating ofthe body of the drumstick from the fingers with some resilient materialwhich can be gripped with firmness and which will not completely inhibitfree motion of the drumstick. Another approach has been to provide someform of locator at the balance point. However, such designs do notestablish freedom from restraint in pivotal movement as the stickrebounds from the drum. Moreover, they do not facilitate grasping andcontrol of the drumstick at the balance point, especially for thestudent learning the fingertip control method of playing drums.

Thus, it is a problem in the art that prior approaches to providingunrestrained pivotal motion of the drumstick do not also enable a userto exercise sufficient control over the drumstick.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

In the following description, for purposes of explanation, specificnumbers, materials and configurations are set forth in order to providea thorough understanding of the invention. It will be apparent, however,to one having ordinary skill in the art that the invention may bepracticed without these specific details. In some instances, well-knownfeatures may be omitted or simplified so as not to obscure the presentinvention. Furthermore, reference in the specification to phrases suchas “one embodiment” or “an embodiment” means that a particular feature,structure or characteristic described in connection with the embodimentis included in at least one embodiment of the invention. The appearancesof phrases such as “in one embodiment” or “in an embodiment” in variousplaces in the specification do not necessarily all refer to the sameembodiment.

FIG. 1 is a perspective view of a drumstick 10 in accordance with anembodiment of the present invention. The drumstick 10 of FIG. 1 mayinclude body 100 and hinge 200. These features will be discussed ingreater detail in connection with FIG. 2.

FIG. 2 shows body 100 and hinge 200 which may include hinge elements 202and 204, and fastener 300. Fastener 300 may simply be a pin that isattachable to the hinge elements 202 and 204. Alternatively, fastener300 may have a more complex geometry and a plurality of parts asdiscussed later herein.

FIG. 3 is a perspective view of a portion of body 100 of drumstick 10.Body 100 may include holes 150, 152, and 154 and may be coupled to hingeelements 202 and 204. The location of hole 150 can only be shownindirectly as the nearest opening of hole 150 (in the view of FIG. 3) isobscured by hinge element 204. The distribution of holes 150, 152, and154 preferably enables a user of drumstick 10 to select the mostdesirable pivot point along the length of body 100 at which to installhinge elements 202 and 204 forming fastener 300. Preferably, hingeelements 202 and 204 may be readily disconnected from one another, forexample by unscrewing a threaded connection, and re-connected within apreferred hole among holes 150, 152, and 154.

FIG. 4 is a sectional view of drumstick 10 in accordance of anembodiment of the present invention. FIG. 4 shows body 100 having holes150, 152, and 154; fastener 300 inserted through hole 150; and hingeelements 202 and 204 having pads 212 and 214, respectively. Pads may beattached to their respective hinge elements to provide more desirablecontact characteristics for a user of the drumstick 10. Alternatively,grip pads 212, 214 may be omitted, and each hinge element 202, 204 couldbe formed using a single integral part.

In this embodiment, hinge elements 202 and 204 may be readilydisconnected from one another and then re-attached within a differentone of three available holes 150, 152, 154. This disconnection andreconnection of hinge elements 202 and 204 may be achieved by unscrewingone of the threaded connections securing hinge elements 202, 204together (see FIG. 5), and then re-connecting the two parts together ina different hole, selected from holes 150, 152, and 154. While athreaded connection is shown in FIG. 5, the present invention is notlimited to this connection means. Other means of connecting two rodstogether may be practiced, such as a press fit, friction fit, etc.Moreover, while three holes are shown in FIGS. 3-4, it will beappreciated that in alternative embodiments, body 100 may include feweror more than three holes.

FIG. 5 is a more detailed schematic sectional view of the percussioninstrument 10 of FIG. 4 in accordance with an embodiment of the presentinvention. Percussion instrument 10 is preferably a drumstick but is notlimited to this embodiment. Percussion instrument 10 may be any one of anumber of other possible percussion instruments, including for instance,a Timpani stick.

Drumstick 10 of FIG. 5 may include body 100 and hinge 200. Hinge 200 mayinclude hinge elements 202 and 204, set screw 310, and/or O-rings 330and 332. Body 100 may be a conventional drumstick body that ispreferably made of wood, though other materials may be employed. Body100 may include flat portions 162, 162, 166, and 168 that are machinedon a portion of body 100 that contacts O-rings 330 and 332 to maximizethe surface area of contact between body 100 and the O-rings 330 and332.

Hinge element 202 may include disk portion 222, shaft 320, open radiusarea (deflection recess) 336 for flexing hinge element 202 upon theapplication of force thereto, and groove 334 for housing O-ring 330.Similarly, hinge element 204 may include disk portion 224, shaft 326,deflection recess 346, and groove 344 for housing O-ring 332.

Fastener 300 may include shafts 320 and 324 of hinge elements 202 and204 respectively. Fastener 300 may further include set screw 310 thatmay be disposed between shafts 320 and 324. Shafts 320 and 324 mayinclude threaded regions 322 and 326, respectively, for engagingsuitable portions of set screw 310. In other embodiments, shafts 320 and324 may be configured to be capable of being directly screwed togetherwithout any need for an intervening set screw. Moreover, othermechanical attachment means may be provided for coupling shaft 320 ofhinge element 202 and shaft 324 of hinge element 204.

Herein, the term “grasping mechanism” may refer to one or more partsincluded within hinge 200. The disk portions 222, 224 of hinge elements202 and 204, respectively, may be referred to herein as grip plates. Itwill be appreciated that grip plates 222, 224 may, but need not be, diskshaped.

Hinge elements 202, 204 may be made of any desired material such as butnot limited to wood, plastic, metal, polytetrafluoroethylene, or anycombination of the foregoing. Shafts 320 324 may be made of the samematerials as disk portions 222 and 224, or alternatively may be made ofmetal to strengthen the threaded connection with set screw 310. Setscrew 310 is preferably made of metal, such as steel or aluminum.Alternatively, set screw 310 could be made of any other desirablematerial such as any of various plastics. O-rings 332 and 334 arepreferably made of a suitably selected rubber. However, other materialsmay be used for O-rings 332, 334 if desired, such as, but not limited toplastic. Disk portions 222, 224 may be made of plastic, metal, or anyother suitable material. While illustrated as disk-shaped, disk portions222, 224 are not limited to having a disk-shaped geometry.

O-rings 330, 332 are disclosed herein as a mechanism for providing a“braking” function for the relative motion between body 100 and hingeelements 202 and 204. However, the present invention is not limited tothe use of O-rings for this purpose, and other braking materials, whichmay be compressible materials, may be employed. Braking materialshowever are not limited to being compressible materials. Any materialsuitable for creating effective braking friction when brought intocontact with the body 100 of drumstick 10 may be employed including butnot limited to rubber, leather, one or more plastics of various types,wood, and/or metal. In other alternative embodiments, a combination ofone or more of the foregoing materials may be employed.

In this section, the attachment means among the various parts arediscussed. The disk portion 222 and shaft portion 320 of hinge element202 may be two separate parts that are joined together. Alternatively,they form a single integral part. In one embodiment, portions 202 and320 of hinge element 202 may be rotationally fixed with respect to oneanother. In other embodiments, shaft 320 may be capable of rotatingfreely with respect to disk portion 222. Arrangements analogous to theabove may be applied to the connection between disk portion 224 andshaft portion 324 of hinge element 204.

Hinge elements 202 and 204 may be joined together by first attaching setscrew 310 to the threaded portion 322 of shaft 320 of hinge element 202,and inserting the shaft portion 320 of hinge element 202 into hole 150within body 100. Thereafter, the threaded portion 326 of shaft 324 ofhinge element 324 may be threaded onto the free end of set screw 310.Once attached onto their respective ends of set screw 310, hingeelements 202 and 204 may be turned with respect to one another to securea final attachment between the two parts. In another approach, the aboveprocess may be repeated in reverse, with the set screw 310 being firstattached to hinge element 204, and hinge element 202 being threaded ontothe assembly of set screw 310 and hinge element 204 within the interiorof hole 150 of body 100.

Having described the individual parts, the materials the parts may bemade of, and the interconnections between the parts, it remains todescribe the operation of a preferred embodiment of the drumstick 10 ofFIG. 5. Once fully assembled, and with no external force applied toforce hinge elements 202 and 204 together, the body 100 of drumstick 10is preferably pivotally mobile with respect to fastener 300 without anyhindrance. A user may pick up drumstick 10 and hold it using diskportions (grip plates) 222 and 224 of hinge elements 202 and 204,respectively.

The user preferably initially holds the grip plates 222, 224 so as toapply force substantially at the center of the grip plates 222, 224 andthereby avoid deflecting the periphery of plates 222, 224 toward theo-rings 330, 332. In this manner, using the initial grasping position,body 100 is preferably freely pivotally mobile with respect to fastener300, thereby enabling the desirable free rotational motion of body 100for both learning and performing purposes.

Another benefit of using O-rings 330 and 332 is to prevent anundesirable clicking sound upon the impact of the striking end ofdrumstick 10, or other type of percussion instrument, with a drum skin,or other percussion surface. The possibility of a clicking sound uponimpact of the drumstick with a drum skin arises from the presence of theapparatus of hinge 200 within and near body 100. An impact between body100 and any portion of hinge 200 may produce the undesired clickingsound. The placement of O-rings 330 and 332 in the locations shown inFIG. 5 preferably operates to massively reduce and/or eliminate theundesired clicking sound by cushioning any undesired impact betweenhinge elements 202, 204 and body 100. It is noted that devices otherthan O-rings 330 and 332 may be employed to prevent the undesired impactbetween parts of hinge 200 and body 100.

When a user of drumstick 10 wishes to limit the rotational speed and/orthe angular displacement of body 100 with respect to fastener 300, theuser may shift the location of the compressive holding force on gripplates 222, 224 so as to deflect the edges of grip plates 222 and 224about deflection recesses 334 and 344 respectively, and in turn causeO-rings 330 and 332 to impinge on body 100 of drumstick 10, whichthereby operates to hinder the rotational motion of body 100 withrespect to fastener 300. In this manner, the rotational speed and/or theangular motion range of body 100 with respect to fastener 300 may becontrolled as a function of the location and magnitude of thecompressive force applied by the user to the respective grip plates 222,224. Moreover, the extent and location of the applied force is under thecontrol of the user of drumstick 10, thereby enabling the user to eitherallow unimpeded pivotal motion of drumstick 10 or to controllably dampenthe motion of drumstick 10 in response to the compressive force appliedby the user.

Another approach to enabling braking of the motion of body 100 withrespect to hinge elements 202 and 204 is shown in FIG. 6. Morespecifically, an alternative approach to enabling the lateral (i.e.transverse-axis) compliance of hinge 200 in response to a compressiveforce so that O-rings 330 and 332 and can be moved toward body 100 toprovide the desired braking function for the motion of body 100 withrespect to hinge elements 202 and 204. Herein, the term “compliancedevice” may refer to the one or more springs 410, 420 of FIG. 6, or anyother mechanism that is operable to enable disk portions 222 and 224 tomove closer together in response to a compressive force applied thereto.

Accordingly, in FIG. 6, the deflection recesses 336, 346 may be omittedas shown. Instead, springs 410 and/or 420 may be employed to enablespring-loaded transverse-axis relative movement between disk portion 402and disk portion 404. We turn now to the operation of the drumstick 10of FIG. 6. When free motion of body 100 with respect to hinge 200(including disk portions 202, 204) is desired, a user preferably holdsdisk portions 222, 224 with a compressive force sufficiently small sothat O-rings 330, 332 do not impart any significant frictional brakingforce against body 100 of drumstick 10. When a user wishes to controlthe pivotal speed and/or extent of pivotal motion of body 100 withrespect to disk portions 222, 224, the user may hold disk portions 222and 224 with a compressive force sufficient to move these two partstowards one another and thereby bring O-rings 330, 332 into contact withbody 100, thereby imparting a frictional braking force to body 100.Thereafter, the braking effect may adjusted by the user by adjusting theamount of compressive force used to hold disk portions 222 and 224. Ifdesired, the compliance features of FIG. 5 and FIG. 6 could be combinedwithin a single embodiment. Thus, one or both of springs 410, 420 couldbe included along with one or more of deflection recesses 336, 346.

While the above embodiments involves using O-rings 330, 332 as theentity making frictional contact with body 100, i.e. as the “brakingmaterial,” the present invention is not limited to the use of O-rings.Other materials having other shapes may be employed either in additionto, or in place of, O-rings 330, 332. Other materials for the frictionalcontact device (i.e. the role of O-rings 330, 332 in FIG. 6) may includebut are not limited to plastic, rubber, wood, fiberglass, metal, or anycombination of the foregoing. In still other embodiments, the presenceof a braking material separate from disk portions 222 and 224 could beomitted entirely. Where such separate braking material is omitted,friction between the internal surfaces of disk portions 202, 204themselves and the body 100 could be used to brake and/or control themotion of body 100 with respect to the disk portions 222 and 224.

While two springs 410, 420 are shown in FIG. 6, it will be appreciatedthat three or more springs could be employed. Moreover, the inventionmay be practiced using only a single spring. Moreover, the one or moresprings providing the needed compliance need not be located as springs410 and 420 are shown in FIG. 6. Compliant devices, such as springs,could be located at any point that would allow disk portions 222 and 224move closer together upon the application of compressive force betweenthese two parts.

In one embodiment, a detent mechanism (not shown) could be employedalong the structural path from disk portion 222 and 224 to establish athreshold force level below which disk portions 222 and 224 would notmove closer together. At compressive force levels above thedetent-mechanism compressive-force threshold, the compressive forcewould begin to force disk portions 222 and 224 together and initiate thebraking function discussed above.

One or more embodiments of the present provide the benefits of enablingthe player to visualize and feel the rebound; enabling the player tovisualize and feel how a loose grip can benefit playing; enabling theplayer to work on velocity strokes, facilitating the whipping motion ofthe Moeller Technique; promoting finger technique for the Timpanitechnique; forcing the player to hold the stick in the correct manner bygripping the pads between the thumb and index finger; and/or allowingthe player to have control of the stick by squeezing the pads for moretechnical playing such as for double strokes and buzz rolls.

In alternative embodiments, the following variations could be practicedto benefit various embodiments of the invention: (1) the use ofdifferent hole diameters; (2) the use of different hole locations; (3)the use of a different size or type of stick; (4) the use of a differentdrum stick tip (wood or nylon); (5) the use of a timpani stick; (6) avariation in the diameter of the portion of fastener 300 extendingthough hole 150; (7) the use of a different diameter (or shape) of thedisk portions 222, 224 of the hinge elements 202, 204; and/or (8) theuse of different means of securing together the shaft portions 320, 324that engage one another within hole 150.
